Ka Band Compact TE21 Tracking Feed System

This paper deals with the design of compact TE
21
based monopulse tracking feed system in Ka Band for satellite communication. It also deals with the coupling mechanism of TE
21
mode by using slots along the circular waveguide. The paper describes the design of the axial corrugated horn used for illuminating the reflector antennas in communication satellites. It also reports the integrated performance of TE
21
Tracking coupler and axial corrugated feed with a septum polarizer. The proposed structure was designed for the frequency range of 22.5 GHz to 27.0 GHz.
